This is not a resolved issue. There are still large uncertainties in modelling ISM dust growth and stellar yields. On the observational side, the dust mass measurements of most sources are still uncertain as they rely on limited ALMA continuum measurements. The stellar masses, gas-phase metallicities, and star formation histories of these sources are also critical ingredients in the dust formation and evolution modelling, but so far these measurements are either non-existent (in the case of metallicities) or very uncertain (in the case of the stellar masses and star formation histories; [1]}). Future observations of the rest-frame optical emission of EoR galaxies with the JWST will be critical to constrain these properties (e.g., [2]}, [3]}).
